* Project:      Cmod S6 ZipCPU demonstration
*
* Purpose:      This script provides a description of the Cmod S6 Zip CPU
*               build for the purposes of where to place memory when linking.
*
*       This script is different from the cmod.ld script in that this script
*       places specific pieces of code into RAM rather than FLASH.  This is to
*       speed up those particular pieces of code.  This script also depends
*       upon a bootloader to load the RAM sections into RAM with their initial
*       values.
